PlainDiagram Embed
An embeddable widget for SaaS docs and wikis that lets users collaboratively edit ASCII/UTF-8 diagrams directly in a web page and export to TXT, JSON, or PNG.
Documentation and developer-experience teams at SaaS companies who maintain README, changelog, and architecture diagrams

- Per-page version history tied to documentation commits
- Theme presets that match your docs site (light/dark, mono fonts)
